BURNER FOR LIGHTING OR HEATING WITH NATURAL OR ARTIFICIAL GAS.

SPECIFICATION forming part of Letters Patent No. 492,179, dated February21, 1893. Application filed February 29, 1892 Serial No. 423,437. (Nomodel.)

To all w/wm, it may concern:

Be it known that I, GEORGE W. ZEIGLER, a citizen of the United States,residing at Anderson, Madison county, Indiana, have invented certain newand useful Improvements in Burners for Lighting and Heating Purposes;and I do hereby declare the following to be a sufficiently full, clear,and exact description thereof to enable others skilled in the art tomake and use the said invention.

This invention relates to burners for converting oils into gas andburning the gas and also for super-heating and burning natui'al andartificial gas and obtaining therefrom the maximum degree of heat andlight, as will more fully hereinafter appear.

The invention consists in certain novel features of construction andcombinations of parts that will be fully hereinafter described andpointed out in the claims.

Figure 1 represents a vertical section of the burner, Fig. 2 a side viewof a modified form of a supply-pipe, Figs. 3, 4t and 5 detail views of aclamping nut or cap, and Figs. 6 and 7, respectively, a side and abottom view of the inner cone of the burner.

Referring to the drawings, which show one form of my burner, the letterA designates the pipe which supplies or conducts the gas or hydrocarbonoils to the burner proper which is secured removably on itslower end.When the burner is used for lighting purposes it is attached to thelower end of the pipe, as shown in the drawings, but when it is used ina stove for heating purposes it should be inverted, as is evident. Abovethe burner the supplypipe is bent upon itself one or two times to form asuper-heating coil A, as shown in Fig.

1,0r it may be formed into a plain spiral coil as shown in Fig. 2, asmay be desired.

Screwed on the lower threaded end of the pipe Ais the upwardly-extendingneck or tube E of the cone E, which is truncated and provided with airopenings a in its upper end and a central interior-1y threaded passageto extending up through the neck E.

Screwed into the lower end of the passage a is a short pipe A which isan extension of the supply-pipe A, the lower end of this pipe A beingclosed to prevent the escape of gas. This extension may or may not beemployed, it being only desirable to the extent that it assists inheating the gas before being supplied to the burner.

Formed around the upper and lower edges of the cone E are annularflanges, lettered,

. respectively, b b, the latter being provided with numerous verticalslits or passages 79 for the issuance of the gas. An outer cone D isfitted down over the inner cone, its interior surface fitting closelyagainst the flanges b b, and its inwardly-extending shoulder D, at itsupper end, resting on the upper end of the inner cone, this flange Dterminating short of the air openings Ct in order not to cover the same.The lower edge of the outer cone terminates even or approximately evenwith the lower edge of the inner cone. Lateral gas-passages 0 connectthe interior of the supply pipe to the annular space formed by flangesb 1) between the two cones, these passages being formed radially in thetop of the inner cone and as many of them as is desired being employed.

The operation of this burner will be evident from the foregoingdescription. The gas in passing down through the coiled supply-pipe ishighly heated before entrance into the burner, Where it isfurtherlieated before being burned. In order to concentrate theascending heat-currents upon the coil I inclose the same in anopen-ended funnel or drum F, the lower open end of which embraces theburner and collects the hot air and gases and guides the same upwardaround the coil, as is obvious. The gas passes down through the pipe A,through passages a and into the annular spaces between the cones, fromwhence it issues in numerous small jets,

through the passages b" formed in flange b,-

the gas in its passage through the burner being highly superheated so asto produce a perfect combustion and the maximum degree of heat andlight. When oil is used instead of gas the same is vaporized in the coiland passages before reaching the burner, as is evident. To securely butremovably clamp the outer cone down tightly upon the upperend of theinner cone and form a gas-tight joint therewith I screw a clamping-nut Gdown upon the cone, this nut being screwed upon the neck E of the innercone and provided with lugs G on its underside to bear against the coneD. By a few turns of this nut the two cones may be separated forcleaning &c- While the burner is in operation, air and flamescontinually pass up through the inner cone, the hot air and gasespassing up through passages a and out through the passages formed by thelugs on the nut G, whereby the air and gases are highly heated beforestriking the supply-coil. The flames of the numerous small jets blendand form practically a single continuous circular flame, a portion ofwhich (when the burner is used in the position shown) turns up inside ofthe burner and a portion up on the outside thereof. The use of numeroussmall jets economizes in the use of the gas and intensifies the lightand heat, each passage forming a small burner from which the gas issuesat the desired pressure. It will be observed thatthe interior of theouter cone bears tightly against the flanges and forms a gas-tight jointtherewith, the flanges being beveled correspondingly with the interiorof the outer cone, thereby forming a close chamber for the generationand commingling of the gases.

The globe and other usual parts may be attached to the burner in anyordinary or approved manner and, if desired, the concentrating casing Fmay be covered with asbestus F for hall or street lamps as shown inFig. 1. Other minor changes may be made without departing from theinvention.

Having thus fully described my invention, what I claim is 1. Thecombination in a burner, of a truncated cone E having formed on it, atits upper and lower edges, exterior annular flanges 19 b, the latterflange being provided with a series of vertical grooves, a supply-pipeconnected to said cone and communicating by lateral passages with theannular chamber between the flanges, an outer truncated cone D fitteddown over the inner cone and having its interior surface bearing closelyagainst the flanges on the inner cone, so as to make a tight jointtherewith and form a chamber between the two cones and the flanges, andmeans for tightly clamping the outer cone down on the inner cone,substantially as described.

2. The combination of an inner truncated cone provided with exteriorflanges, beveled correspondingly with the interior surface of the outercone, the lower one of these flanges being provided with numerousvertical slits 0r grooves a supply pipe, connected by passages to thechamber between the cones, an outer truncated cone fitted down over theinner cone and having its beveled interior surface bearing on theflanges on the inner cone and forming a gas-tight joint therewith, theouter cone being provided with an inwardlyextending shoulder bearing onthe top of the inner cone, and means for clamping the two cones tightlytogether, one within the other substantially as described.

3. The combination of a supply pipe, an inner truncated cone providedwith a neck E projecting from its upper end into which the supply pipeis secured, said cone being also provided with exterior flanges 13.13,and lateral gas passages c in its top these passages leading to thespace between the cones, an open ended outer cone fitted down over theflanges of the inner cone, and provided with an inwardly-extendingflange D bearing 011 the upper end of the inner cone and a nut threadedand screwed on the neck of the inner cone and bearing on the top of theouter cone, substantially as described.

4:. The combination of a supplypipe, a hollow truncated cone screwedthereto and provided with openings to in its top, an outer cone fitteddown over the inner cone and a nutG screwed down on the cones andprovided with lugs G onits under side to permit the passage of air underthe nut, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

GEORGE WV. ZEIGLER.
